Instagram Tracker

A local-only browser extension that tells you who doesn't follow you back on Instagram, and keeps a durable log of who unfollows you over time.

Download & install

There's no Chrome Web Store listing — install it manually ("sideload"):

Go to the Releases page and download instagram-tracker-extension.zip from the latest release.
Unzip it to a folder you'll keep around (don't delete it after installing — Chrome loads the extension from that folder).
Open chrome://extensions (or edge://extensions on Edge).
Turn on Developer mode (toggle in the top-right corner).
Click Load unpacked and select the unzipped folder.
Click the extension's icon in the toolbar to open the results page, then click Scan now while logged in to Instagram.

To update later: download the new release's zip, unzip it over the same folder, then hit the reload icon for the extension on chrome://extensions.

Read-only: it only fetches your following list, it never follows or unfollows anyone.
All data (scan results, whitelist, unfollower log) stays in your browser's IndexedDB — nothing is sent anywhere else.
Uses Instagram's private, undocumented endpoints via your own logged-in session, which is against Instagram's Terms of Service even though it's read-only. Use at your own risk (temporary blocks, checkpoints, or suspension are possible). Not affiliated with Instagram/Meta.
